Description
【0001】[0001]
本考案は、例えば、異なる径の配管を接続するための管継手に関するものであ る。 The present invention relates to a pipe joint for connecting pipes having different diameters, for example.
【0002】[0002]
図2は異なる径の配管を接続するために、従来から使用されてきた管継手の使 用状態の断面図である。管継手1は、テーパ状の管継手本体2の両端にそれぞれ フランジ3,4が径方向に突出して形成され、小口径の配管5と大口径の配管6 の端部に形成されたフランジ7,8と接合している。 FIG. 2 is a sectional view of a pipe joint that has been conventionally used for connecting pipes having different diameters. In the pipe joint 1, flanges 3 and 4 are formed at both ends of a tapered pipe joint body 2 so as to project in the radial direction, and flanges 7 formed at ends of a small-diameter pipe 5 and a large-diameter pipe 6, It is joined with 8.

異なる径の配管5,6を接続する場合は、流れのはく離や乱れを少なくするた めに、管継手1のテーパが急にならないようにしなければならず、配管5,6の 面間寸法を短くするのはおのずと制限が生じる。 When connecting pipes 5 and 6 with different diameters, in order to reduce flow separation and turbulence, it is necessary to prevent the taper of pipe fitting 1 from becoming steep, Naturally, there is a limit to shortening.
【0004】 しかし、設計等の事情で面間寸法を短くしなければならない場合があるが、図 3のように従来の管継手1を短くすると、流れのはく離や乱れ、騒音が生じ、ま た、エネルギーが損失するという問題点があった。However, there are cases in which the face-to-face dimension must be shortened for reasons such as design, but when the conventional pipe joint 1 is shortened as shown in FIG. 3, flow separation, turbulence, and noise occur, and However, there was a problem that energy was lost.
【0005】 特に、ポンプ直前に管継手1を設ける様な場合は、流れのはく離や乱れがある と、ポンプ性能に影響があるため、管路内の流れにはく離や乱れを少なくする必 要がある。Particularly, in the case where the pipe joint 1 is provided immediately before the pump, if the flow separation or turbulence affects the pump performance, it is necessary to reduce the separation or turbulence in the flow in the pipeline. is there.
【0006】 本考案は、上記のような問題点を解決するためになされたもので、異口径の配 管を接続する場合でも短面間の接続を可能とした管継手を提供することを目的と している。The present invention has been made to solve the above problems, and an object of the present invention is to provide a pipe joint capable of connecting between short faces even when connecting pipes having different diameters. I am saying.
【0007】[0007]
本考案の管継手は、管継手本体を漸次拡開するテーパ状とし、この管継手本体 の拡開した一方側の外径を大口径の配管の内径と略同じく形成し、管継手本体の 他方側寄り外周面に、大口径の配管を外嵌して接続するためのフランジを設けて いる。 The pipe joint of the present invention has a tapered shape that gradually expands the pipe joint body, and the outer diameter of the expanded one side of the pipe joint body is formed to be substantially the same as the inner diameter of the large-diameter pipe, and the other side of the pipe joint body is formed. A flange for fitting and connecting a large diameter pipe is provided on the outer peripheral surface on the side.
【0008】[0008]
上記構成の管継手は、管継手本体が大口径の配管内に挿入できる分だけ配管の 面間寸法を短くすることができるが、管継手本体はゆるやかなテーパ状をしてい るので、流体が小口径の配管から大口径の配管に移動する場合も、流れのはく離 や乱れが極めて少なくなる。また、流体を大口径の配管側から小口径の配管側に 流す場合でも流体の乱れが少なく、エネルギー損失や騒音も少ない。 The pipe joint with the above configuration can reduce the face-to-face dimension of the pipe by the amount that the pipe joint body can be inserted into a pipe with a large diameter, but the pipe joint body has a gentle taper shape, Even when moving from a small diameter pipe to a large diameter pipe, flow separation and turbulence are extremely small. Moreover, even when the fluid is flowed from the large-diameter pipe side to the small-diameter pipe side, there is little turbulence of the fluid, and energy loss and noise are also small.

以下に本考案の一実施例について、図面を参照しながら説明する。 図1は本考案の第1の実施例の管継手の使用状態の断面図であって、この図に おいて、11が管継手を示し、小口径の配管12と大口径の配管13とを接続し ている。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a pipe joint according to a first embodiment of the present invention in use, in which a pipe joint 11 is shown, and a small-diameter pipe 12 and a large-diameter pipe 13 are shown. Connected.
【0010】 管継手本体14は、漸次拡開してテーパ状をしており、小径の他方側15は小 口径の配管12と同一の直径であって、大径の一方側16の外径は大口径の配管 13の内径に略等しく形成されている。そして、管継手本体14の他方側15の 端部にはフランジ17が径方向に突出して形成され、小口径の配管12のフラン ジ18に当接してボルト等で接続されている。管継手本体14の外周壁の他方近 傍には大口径の配管13のフランジ19と対応するフランジ20が径方向に突出 して設けられ、このフランジ20の位置まで管継手本体14が大口径の配管13 内にスッポリ挿入し、フランジ19,20同士がボルト等で接合されている。The pipe joint body 14 is gradually expanded to form a taper shape, the other side 15 of the small diameter has the same diameter as the pipe 12 of the small diameter, and the outer diameter of the one side 16 of the large diameter is It is formed to be approximately equal to the inner diameter of the large-diameter pipe 13. A flange 17 is formed at the end of the other side 15 of the pipe joint body 14 so as to project in the radial direction. The flange 17 is in contact with the flange 18 of the small-diameter pipe 12 and is connected thereto by bolts or the like. Near the other side of the outer peripheral wall of the pipe joint body 14, a flange 20 corresponding to the flange 19 of the large-diameter pipe 13 is provided so as to project in the radial direction, and the pipe joint body 14 has a large diameter up to the position of the flange 20. The flanges 19 and 20 are joined together by bolts or the like by inserting them into the pipe 13.
【0011】 次に、上記構成の作用を説明する。 流体の流れは小口径の配管12から大口径の配管13の方向に流れている。 この考案の実施例では、管継手本体14が大口径の配管13内に挿入された分だ け配管の接続を短くすることができる。しかし、管継手本体14は十分な長さが あるので、流体が小口径の配管12から大口径の配管13に移動する場合も、流 れのはく離や乱れが極めて少なくなる。従って、騒音やエネルギー損失が極めて 少なくなる。Next, the operation of the above configuration will be described. The fluid flows from the small-diameter pipe 12 to the large-diameter pipe 13. In the embodiment of the present invention, the pipe joint body 14 is inserted into the large-diameter pipe 13 so that the connection of the pipe can be shortened. However, since the pipe joint body 14 has a sufficient length, even when the fluid moves from the small-diameter pipe 12 to the large-diameter pipe 13, the flow separation and turbulence are extremely reduced. Therefore, noise and energy loss are extremely low.
【0012】 上記では、流体の流れは小口径の配管12から大口径の配管13に流れるとし たが、この管継手はかかる方向に流れる場合のみに限定されるものではなく、逆 方向、即ち、大口径の配管13から小口径の配管12に流れる場合であっても使 用できる。この逆の流れの場合も乱れやエネルギー損失、騒音が少なくなる。In the above description, the fluid flow is assumed to flow from the small-diameter pipe 12 to the large-diameter pipe 13, but this pipe joint is not limited to the case of flowing in such a direction, and the reverse direction, that is, It can be used even when flowing from the large diameter pipe 13 to the small diameter pipe 12. Also in the case of this reverse flow, turbulence, energy loss, and noise are reduced.
【0013】 なお、管継手本体14の外周壁に形成されたフランジ20を無くし、他方側の フランジ17を大きく形成し、小口径の配管12のフランジ18と大口径の配管 13のフランジ19で他方側15のフランジ17を挟み込み、三者17,18, 19をボルトで締め付けるようにしてもよい。It should be noted that the flange 20 formed on the outer peripheral wall of the pipe joint main body 14 is eliminated and the flange 17 on the other side is formed large, and the flange 18 of the small diameter pipe 12 and the flange 19 of the large diameter pipe 13 are The flange 17 on the side 15 may be sandwiched and the three members 17, 18, 19 may be bolted.
